The radii of two metallic spheres are ...

The radii of two metallic spheres are 5 cm and 10 cm and both carry equal charge of `75 mu C`. If the two spheres are shorted then charge will be transferred-

A

`25mu C` from smaller to bigger

B

`25mu C` from bigger to smaller

C

`5mu C` from smaller to bigger

D

`50mu C` from bigger to smaller

Text Solution

Verified by Experts

The correct Answer is:
A
`Q_(1)= Q_(1 ) + Q_(2)= 150mu C`
`(Q_(1))/(Q_(2)) = (C_(1))/(C_(2))= (1)/(2) rArr Q._(1) = 50mu C`
`Q._(2)= 100mu C`
`25muC` charge will flow from smaller to bigger sphere
